Topological laser in a two-dimensional Su-Schrieffer-Heeger lattice with artificial gauge flux
Yi-Ling Zhang, Yang Liu, Zhi-Kang Lin +1
Topological lasers, known for their robustness and unique features originating from nontrivial topology, have recently become a focal point of research in photonics. In this work,…
Hybrid skin-topological effect in non-Hermitian checkerboard lattices with large Chern numbers
Yi-Ling Zhang, Li-Wei Wang, Yang Liu +2
Non-Hermitian topology provides a research frontier for exploring topological phenomena, revealing novel topological effects and driving the development of emergent materials and p…
Topologically integrated photonic biosensor circuits
Ze-Lin Kong, Yang Liu, Jian-Hua Jiang
Integrated nanophotonic biosensors offer a promising route toward future biomedical detection applications that may enable inexpensive, portable, and sensitive diagnosis of disease…
Photonic biosensing via Su-Schrieffer-Heeger boundary modes
Yang Liu, Jian-Hua Jiang
We propose a conceptual device for multiplexed biosensor in a photonic crystal chip based on the Su-Schrieffer-Heeger mechanism. Remarkably, the proposed biosensor can identify thr…
